Question 12

What is polygenic genes?

Answer 12

“many genes” - single trait controlled by 2 or more genes

Question 13

What partly determines the phenotype?

Answer 13

genotype

Question 14

What are environmental conditions?

Answer 14

shows how the gene are expressed & influence traits

Question 15

Genes provide a plan for development but what does it depend on?

Answer 15

environment

Answer 16

For who gets blood to who

Question 17

Answer 17

ii

Question 18

What is the genotype for TYPE A blood?

Answer 18

IAIA or IAi

Question 19

What is the genotype for TYPE B blood?

Answer 19

IBIB or IBi

Question 20

What is the genotype for TYPE AB blood?

Answer 20

IAIB

Question 21

How many antigens does the blood TYPE O have?

Answer 21

none - that’s why they can give blood to every type of blood.

Question 22

Where is the heterozygous phenotype located?

Answer 22

between the homozygous phenotypes (blending)
